TORQUE VALUES FOR FASTENERS
GENERAL INFORMATION
1. The torque values in the following chart are for fasteners
hat have a light application of oil on the threads.
2. If the fasteners are dry, increase the torque values by ten
percent (10%).
3. If the fasteners have a heavy application of oil on the
threads, decrease the torque values by ten percent (10%).
4. If you do not know the size of the fastener that is being
installed, measure the fastener. Use the following procedure.
American Standard Fasteners
a. Measure the diameter of the threads in inches. dimen-

X DIMENSION = (EXAMPLE

Figure 2-103. Determining Size Of American
Standard Fastener.
b. Count the amount of threads there are in one inch (1.0
inch) (Figure 2-103). Example of an American Standard size
fastener is .50 - 13. The .50 is the diameter of the fastener in
inches (dimension X). The 13 is the number of threads in one
inch (1.0 inch).
Metric Fasteners
a. Measure the diameter of the threads in millimeters
(dimension X) (Figure 2-104).
X DIMENSION = (EXAMPLE MB OR 8. mm)
Y DIMENSION= DISTANCE OF 10 THREADS
Figure 2-104. Determining Size Of Metric Fastener.
b. Measure the distance of ten (10) threads, point to point
in millimeters (mm), dimension Y. Make a note of dimension Y
(Figure 2-104).
c. Divide dimension Y by ten (10). The result will be the
distance between two threads or pitch. Example of a Metric size
fastener is M8 x 1.25. The M8 is the diameter of the fastener in
millimeters (mm) (dimension X). The 1.25 is the distance
between two threads or pitch.
5. Compare the size offastener measured in step 4 to the list
of fasteners in the following chart to find the correct torque
value.
